CO2 Monitor Switchbot Meter Pro — CO2, Temperature & Humidity Measurement, LCD, Battery (AA), ABS Housing, 5 V, Temp Range -20–80°C

Switchbot Meter Pro — CO2, Temperature & Humidity Measurement is a portable indoor air quality monitor with an integrated LCD that reports carbon dioxide concentration, ambient temperature and relative humidity. The unit uses AA battery power (5 V supply equivalence), is housed in white ABS plastic and includes an internal clock for time-stamped readings. Its compact design and clear display make it suitable for homes, offices and classrooms where monitoring ventilation and comfort is required.

Advantages

The Switchbot Meter Pro provides continuous, easy-to-read measurements of CO2, temperature and humidity on a built-in LCD, enabling quick assessment of indoor air quality without additional equipment. The ABS housing and battery power make the device portable and simple to install or move between rooms. A visible clock and clear numeric display help track conditions over time, and the device supports local data visibility for routine monitoring.

Suitable for

• Home rooms (living room, kitchen, bedrooms) where ventilation checks are needed
• Offices and meeting rooms to monitor occupancy-related CO2 rises
• Classrooms and small educational spaces to assess air renewal needs
• Portable spot checks during inspections or when assessing HVAC performance

When it may not be suitable

The Meter Pro is designed for general indoor air quality monitoring and is not a certified laboratory instrument for high-precision scientific or industrial applications. It is intended for routine CO2, temperature and humidity checks rather than regulatory compliance testing.

Key specifications

• Measured parameters: CO2 concentration, indoor temperature, relative humidity
• Temperature measurement range: -20 to 80 °C
• Display: built-in LCD with clock function
• Power: AA battery operation (nominal 5 V supply equivalence)
• Housing material: ABS plastic
• Colour: white
• Weight: 0.154 kg

How to use

Place the Switchbot Meter Pro in the zone you want to monitor at typical breathing height and away from direct airflow sources such as vents or open windows for representative readings. Power the device with AA batteries and allow it to stabilise for several minutes before taking measurements. Read CO2, temperature and humidity values directly on the LCD; use the device controls to refresh readings or switch display units if available. For periodic checks, move the meter between rooms and note variations in concentration to decide on ventilation actions.

What to consider before purchase

• Intended use: suitable for general indoor monitoring, not a laboratory-grade analyser
• Power source preference: battery operation offers portability but check battery life expectations
• Placement needs: will you mount it on a wall or place it on a shelf or desk?
• Display visibility: confirm LCD size and readability meet your viewing distance requirements

Usage recommendations

For reliable comparison of indoor air quality over time, record measurements under similar placement and occupancy conditions. If CO2 readings consistently exceed recommended indoor levels, increase ventilation or reduce occupancy until concentrations fall to acceptable ranges.
